Parts of Earth Assignment

1. Crust
2. Inner core
3. Crust
4. The plates are moving apart everyday.
5. Mantle crust
6. Divergent boundary.
7. An earthquake happening.
8. One plate move under another plate.
9. Divergent boundaries Ocean ridge, divergent boundary
10. When two continent plates move apart a valley develops. The crust widens and the volcanoes formed are very active. Streams and rivers come into the valley and lakes are formed. As the crust gets wider along the boundary, some parts of the continent breaks off.

What are Minerals?
1.It must occur naturally, it must be inorganic, it must be a solid, it must possess an orderly internal structure like its atoms must need arranged in a definite pattern, it must have a definite chemical composition that may vary within specified limits organic has carbon
2.Hardness, optical properties, crystal structure
3.Carbonates, CO3 -2, oxides O2, sulfur S-2

"Life Cycle of Copper/BS4"

1.Amount of useful ore at the site, percent of metal in the ore, typing of mining and processing needed to extract the metal from its ore, distance of the from metal refining facility and markets, metal's supply versus demand status. mining, reduction, melted, mold it, recycled copper or trashed

2.First copper ores mined from 35 to 88% of copper. Mining less than 1% copper. Copper processed to produce metallic copper. Than transformed into a variety of useful materials.

1. Malleability and ductility: coins

Electrical conductivity: wires
Thermal conductivity: thermater
Chemical reactivity: easy to test other materials
Resistance to corrosion: melting
Useful alloys formed: internet
Color and luster: making new atoms

2.a The copper wound be old and won't work
b. because we need to save some recycling in the future.

3. a. By making more. credit cards, cash money, checks
b. Everyone using plastic. writing,cell phones, walkie talkies
c. People using wind mills. solar planel,
d. People going outside. alumn cans-cheap, silver- high cost

Questions from video
1. The penny turns black then shiny crystals start to form on the surface then the penny turns light blue.
2.The ions gain 1 electron and become silver atoms.
3.Silver ion is gaining an electron from a copper atoms called reduction. Then a copper atom is leaving it's two electrons in the metal structure forming copper 3 ion called oxidation.
4.Oxidation is where an atom losing 2 electrons in the metal structure forming a different ion 5.Reduction is when an ion gains an electron from an atom.
6.They lose 2 electrons.
7.Two silver ions gain an electron.
8.Silver ion (electrons)

(No data table -10)
1.a. both
b. the whooper change color and with the heat going in ward the crucible make the flame change the copper.
2. a. the copper change color and the crucible turned orange.
b. because the copper color faded into black and grey, the mass also changed after we heated it. The copper sticks to the crucible.
3.a. The mass went up by 1%
b. Because nothing left and the mass changed because of the air and the amount of stirring. (How did the stirring effect the mass? What do you mean by "nothing left"?)
Activity Series of metals

Describe what happens to the size of the Magnesium atoms as they change into Magnesium ions.
5.The cloud around the atoms goes away. The size doesn't change. smaller, lose electrons
Do the same for Zinc.
5.The same thing happen like the magnesium, the cloud disappear but the size stay the same. smaller
Describe what happens when Zn2+(aq) reaction with Mg(s).
5.cloud goes to zinc and one of the magnesium has no cloud and floats away. z gain
Describe what happens when Mg2+(aq) reacts with Zn(s).
5.The magnesium gets close to zinc then goes away. like magnesium magnes wants to lose electrons active wants to lose electrons
6.For the magnesium 2+ and copper there was no reaction. Some thing with copper and zinc 2+ there was no reaction.
6.For magnesium and copper 2+ there was a reaction. One copper got one of the magnesium cloud and the magnesium with no cloud floated away. The other copper got clouds by the 4 magnesium switching clouds. Then another magnesium with no cloud floated away. The same thing with zinc and copper 2+.
7. Mg and Ag+ would be a non reaction. Zn and Ag+ would also be non reaction. Ag and Mg+2 would be a reaction. Ag and Zn+2 would also be a reaction. Silver ions and zinc metals react good with each other.
8. Manganese
Zinc
Copper
Silver
Chem Quandary 1/Building skills 5
Gold and silver made things. They didn’t react with other things. Copper also because it was right in front of their eyes and didn't react with lead or manganese. they were right in front of them

1. a. The elements are getting less reactive. b. The first group.c. The last group.
2. a. Yes.

b. No.
c. 2a because they have uneven amount of electrons which would make another metal. 2b because they have the same amount of electrons and they would form a neutral atom.
3. a. No.
b. Where they are found and how they are mined, and how they are import and export.
Modeling Matter
1. a Zn: Zn:>Zn+2+2e- oxidation
b. Ag. Ag+ +1e->Ag. reduction
2. Zn: two electrons are going away. Oxidation. Ag::. gains 5 electrons to be even in the electron-dot structure.
Reduction.
Cu(s) +2Ag+(ag)>Cu2+(ag)=2Ag(s)
3. a. Ag+ Cu:
b. Cu Ag+
4. So that they can cross each other out and because their will be even numbers on both sides.
5. a. Ag+ ions
b. An element helping another element causing the element to lose electrons.
6. Zn: + Cu: + Ag+ +Ag+ > Zn2+(aq)+ Cu(s) :Zn(s) + Cu2+>Zn2+(aq)+:Cu(s)
7. a. Cu Zn:
b. Zn Cu2+
8. Ag+ ions for both Cu2+
9. The amount of Ag ions Zn:
10. 7.a.) Zn b. Mg on product the Cu is reduction, Zn is oxidation
8.) Mg ions on product the Cu is reduction, Zn is oxidation

Questions from lab

1. Silver magnesium
2. Zinc silver
3. Magnesium any element less reactive than silver
4. Silver, magnesium, zinc, copper mag., zinc, copper, silver
5. Copper is lest reactive.
6. a. Zinc because it doesn't reactive with everything. silver

b. Because it a has other uses in this world. expesense
7. a. silver
b. Magnesium
8. a.no yes
b.none copper, magnesium

Part 1 Lab: Separating the copper

mass of filter with nothing	mass of filter with pure copper	mass of filter with soild copper
first: 0.70g	1.67g	0.97g
second: 0.71g	0.81g	0.10g

mixing 1m of HCl with copper oxide
( the black copper turned copper color again)
( turns yellow)
1 gram of copper = 2 zinc: 1.29g
Part 2
reacts right away when in the beaker ( bubbles start)
over night the color changed to clear, zinc is broken into tiny pieces.

Building Skills: Hydrocarbon Boiling Point
1a They go in alaphabeth order.
b No because there is so many atoms and molecules that it would be so hard to find things.
2a Lowest boiling point to the highest boiling point.
b Hydrocarbon Boiling Point

Propane	-42.1
Butane	-0.5

Boiling Point Of Alkane Isomers Building Skills 3
1. The boiling point gets lower.
a. 98.4 C
b. 92.0 C
c. 79.2 C

3.a. They are all branch out and have chains, they all start with one carbon and three hydronges. Lower boiling point.
b. higher boiling point parent chain longer
4. The more branches the lower the boiling point gets. As the parent chain gets longer the boiling point decreases.
